Actually, Google has already diversified quite a bit. It started out by selling search appliances and search ads. It then started a contextual text-ad network comprised of mom-and-pop publishers, corporate megasites, and nearly everyone in between. Later, it added display-ad serving with DoubleClick. Now it's acting as a middleman between third-party advertising networks and AdSense publishers. Anyone who thinks those diverse businesses fit under the heading of "one-trick pony" doesn't understand how different those businesses are.
